Description

Technical Field

[0001] The utility model relates to the technical field of mechanized assembly, in particular to an assembly line. Background Art

[0002] In the field of mechanical assembly, some companies adopt the bench-type assembly mode, but the bench-type assembly mode has limited working space and low assembly efficiency; based on this, some companies adopt the "one-flow" assembly mode to improve production efficiency. In the existing "one-flow" assembly mode, AGV traction technology or transfer tracks (such as conveyor belts or conveyor rollers) are generally used to achieve the transfer of products between different workstations. However, when using AGV traction technology to achieve one-way circulation flow assembly, the existing AGV traction technology has problems with AGV charging and discharging and high failure rate, which will affect the stability of the production process and production efficiency. Setting up a dedicated transfer track requires a lot of ground space, which is not conducive to the production layout in the production workshop. Utility Model Content

In addition, since it is not necessary to use AGV traction technology to drive the carrier to move, the impact of the immaturity of the existing AGV traction technology on production stability can be avoided.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] First of all, it should be noted that the assembly line in the utility model is applicable to the scenario where "one-flow" assembly is required in the industrial production process. The so-called "one-flow" assembly means that in the production process, the product or part moves only one unit at a time, directly from one workstation to the next workstation, rather than batch production and movement.

[0049] like Figure 1-Figure 11As shown, the assembly line in the embodiment of the utility model includes a support component, a drive component, a carrier 4 (a structural component for carrying products, such as a trolley, a pallet or a skateboard, etc.) and a connecting component, wherein the support component includes a support plate having an annular opening 15 on the surface, the drive component is arranged below the support plate, the carrier 4 is located on the top of the support plate, and the connecting component is arranged on the drive component, which can extend to the top of the support plate and connect to the carrier 4, so that the carrier 4 can move along the annular opening 15 under the drive of the drive component, that is, the connecting component arranged on the drive component has at least two states, one is a state when connected to the carrier 4, in which state, the connecting component partially extends to the top of the support plate, and the part of the connecting component extending above the support plate is connected to the carrier 4; the other is a state when not connected to the carrier 4, in which state, the connecting component is completely located below the support plate.

[0050] It should be noted that, regarding the shape of the annular opening 15 on the support plate, during specific implementation, it is necessary to perform an adaptive design based on the specific needs of the production layout. The production layout here refers to the location layout of different workstations in the production workshop, which should ensure that the workstations in the production workshop (including loading workstations, unloading workstations, and workstations for processing products) are located on both sides (or one side) of the annular opening 15 so that the carrier 4 can transfer products to different workstations.

[0051] When the assembly line is running, the connection component is controlled to extend above the support plate and connected to the carrier 4. Then, the drive component is started and the product to be processed is placed on the carrier 4 at the loading workstation. The carrier 4 carries the product to different workstations until the product processing is completed and the unloading is completed at the unloading workstation.

[0052] Since the driving components of the above-mentioned assembly line are arranged under the support plate, and the surface of the support plate can replace the floor of the production workshop as the walking surface or the bearing surface of the workstation, the impact of the setting of the assembly line on the production layout can be reduced. At the same time, since the connection components can be hidden under the support plate, when the logistics transfer needs to pass through the assembly line, it is only necessary to hide the connection components of the corresponding area under the support plate and move the carrier 4 away, which is conducive to the planning of the logistics transfer route in the production workshop. In addition, since it is not necessary to use AGV traction technology to drive the carrier 4 to move, the impact of the immaturity of the existing AGV traction technology on production stability can be avoided.

[0053] Furthermore, in some preferred embodiments, in order to enable the support plate to better replace the ground of the assembly area (i.e., the area where the assembly line is installed in the production workshop) to facilitate production layout, an installation groove can be set in the production workshop corresponding to the area where the assembly line is installed, and the bottom of the installation groove is used as the foundation 3 for fixing the support assembly, and the support plate is made flush with the ground of other areas of the production workshop.

[0054] In addition, it should be noted that the above-mentioned upper side of the support plate refers to the area on the side of the support plate away from the ground when the support plate is parallel to the ground or arranged at a certain angle to the ground. Correspondingly, the lower side of the support plate refers to the area on the side of the support plate close to the ground (i.e., the area between the support plate and the ground) when the support plate is parallel to the ground or arranged at a certain angle to the ground.

[0055] like Figure 2 As shown, the driving assembly of the assembly line includes a driving member 9 and a chain track assembly that is transmission-connected to the driving member 9, wherein the chain track assembly includes a plurality of sprocket groups and a ring-shaped chain 10, at least one sprocket group is transmission-connected to the driving member 9, and a plurality of sprocket groups are respectively arranged at the inflection points of the ring-shaped opening 15, and meshed with the chain 10, so that the chain 10 is arranged corresponding to the ring-shaped opening 15. This arrangement is not only simple in structure, but also stable, reliable, and easy to maintain, which is conducive to improving production stability and reducing equipment and operation and maintenance costs. At the same time, the annular chain 10 has strong adaptability, which can reduce the constraints of the driving assembly on the shape of the annular opening 15, and is more conducive to the production layout in the production workshop.

[0056] It should be noted that the inflection point of the annular opening 15 refers to the place where the extension direction of the annular opening 15 changes. For example, Figure 1 As shown, when the annular opening 15 is a quadrilateral, the annular opening 15 refers to the angle between two adjacent sides of the quadrilateral.

[0057] Furthermore, in some embodiments, the driving member 9 is a driving motor, such as Figure 2 As shown, the drive motor is fixedly arranged on the foundation 3, and the output end of the drive motor is connected to the sprocket group in a transmission manner. The transmission connection can be realized by a gear group structure or a belt structure, and can be adaptively designed according to needs. Further, a reducer is connected to the output end of the drive motor in a transmission manner to increase the output torque.

[0058] It should be noted that the number of drive motors can be adaptively designed as needed, but the output power of the drive motors should be able to meet the transportation requirements. For example, in some embodiments, only one drive motor is provided, and the drive motor is arranged near a sprocket group and is in driving connection with the sprocket group. In other embodiments, three drive motors are provided, and the three drive motors are respectively arranged near different sprocket groups and are respectively in driving connection with different sprocket groups.

[0059] Furthermore, on the basis of setting up a plurality of driving motors, a control encoder is set to control the starting number of the plurality of driving motors, and to control the synchronous operation of the plurality of motors when the plurality of driving motors work at the same time.

[0060] In addition, if Figure 6 and Figure 7 As shown, in some embodiments, the sprocket assembly includes a fixed sleeve 16 and a sprocket 8 sleeved on the fixed sleeve 16, wherein the fixed sleeve 16 is in driving connection with the driving member 9 so that the sprocket assembly can rotate around the axis of the fixed sleeve 16. During the operation of the assembly line, the driving member 9 drives at least one sprocket assembly in the chain track assembly to rotate, and the chain 10 in the chain track assembly moves along the annular opening 15 under the drive of the sprocket assembly, and drives the carrier 4 connected to the chain 10 to move synchronously, thereby realizing the driving of the carrier 4.

[0061] Furthermore, in some preferred embodiments, the chain 10 group includes a plurality of sprockets 8 distributed along the axis direction of the fixed sleeve 16; a plurality of chains 10 are arranged side by side along the axis direction of the fixed sleeve 16, and the plurality of chains 10 are respectively meshed and connected with different sprockets 8 in the sprocket group. In this way, the load on the chain 10 can be dispersed, local overload of the chain 10 can be avoided, and the stability of the equipment operation can be improved.

[0062] Regarding the number of sprockets 8 in a sprocket set, in specific implementation, an adaptive design can be performed as needed, and the present invention does not make specific restrictions on this. For example, two sprockets 8 or three sprockets 8 can be fixedly arranged on the fixed sleeve 16 along its axial direction.

[0063] Further, on the basis of providing multiple sprockets 8, the multiple sprockets 8 are evenly distributed in the axial direction of the fixed sleeve 16. For example, when two sprockets 8 are provided, the sprockets 8 are respectively provided at both ends of the fixed sleeve 16. When three sprockets 8 are provided, the sprockets 8 are respectively provided at both ends and the middle of the fixed sleeve 16. Such a configuration can make the fixed sleeve 16 evenly stressed, thereby improving the stability of the assembly line operation.

[0064] It should be understood that the above only uses the example that the drive assembly includes a chain track assembly to exemplify the drive assembly in the present invention, but the drive assembly in the present invention is not limited to this. For example, in the specific implementation process, a drag chain structure or a belt structure can also be used to replace the chain track assembly in the above text.

[0065] like Figure 3 As shown, in some embodiments, the connection assembly includes a limit seat and a connecting rod 5, wherein the limit seat is fixedly arranged on the chain 10, the connecting rod 5 is slidably connected to the limit seat, and one end of the connecting rod 5 can extend above the support plate to connect the carrier 4. Such a configuration enables the connection assembly to move with the chain 10 and stably connect the carrier 4, thereby realizing the driving of the carrier 4. In addition, the setting of the limit seat can also limit the connecting rod 5 to prevent the connecting rod 5 from deflecting or shaking during the movement, thereby ensuring the stable operation of the carrier 4.

[0066] In addition, a limiting portion is provided between the limiting seat and the connecting rod 5, for limiting the displacement of the connecting rod 5 relative to the limiting seat in its sliding direction; thus, on the one hand, when the connecting assembly is not connected to the carrier 4, the limiting portion can prevent the connecting rod 5 from sliding onto the foundation 3, thereby affecting the next use. On the other hand, when the connecting assembly is connected to the carrier 4, the connecting rod 5 can be prevented from being separated from the limiting seat under the force applied by the carrier 4, thereby ensuring the stable operation of the assembly line.

[0067] Further, in some embodiments, a hole is opened on the limit seat so that the connecting rod 5 passes through the limit seat and is slidably connected to the limit seat, and the connecting rod 5 can rotate relative to the limit seat, and the limit portion includes a limit groove provided on one of the limit seat and the connecting rod 5, and a limit protrusion provided on the other, or the limit portion is a limit protrusion provided on the connecting rod 5. Exemplary:

[0068] In some embodiments, the limit seat is fixed to the chain plate 17 of the chain 10 by bolts, a limit hole is provided on the limit seat, two limit protrusions are provided on the connecting rod 5 along the axial interval, and in the assembled state (i.e., the connecting rod 5 is penetrated and provided on the limit seat), the two limit protrusions on the connecting rod 5 are respectively located on both sides of the limit seat. When the connecting assembly is not connected to the carrier 4, the limit protrusion on the side of the connecting rod 5 close to the support plate is stuck on the upper surface of the limit seat, thereby preventing the rod from sliding onto the foundation 3; when the connecting assembly is in a connected state with the carrier 4, the limit protrusion on the side of the connecting rod 5 away from the support plate is stuck on the lower surface of the limit seat, thereby preventing the connecting rod 5 from being separated from the limit seat under the force applied by the carrier 4.

[0069] It should be noted that the spacing distance between the two limiting protrusions on the connecting rod 5 can be adaptively designed according to the length of the connecting rod 5 that needs to be extended out of the support plate, and the present utility model does not make any specific limitation on this.

[0070] In other embodiments, different from the above embodiments, in this embodiment, the limiting part includes a limiting groove and a limiting protrusion, wherein the limiting groove is an axially extending strip groove 20 provided on the inner wall of the limiting hole, and at least one limiting protrusion on the connecting rod 5 can pass through the limiting hole. In this way, the limiting protrusion on the connecting rod 5 can be misaligned with the strip groove 20 by rotating the connecting rod 5, so that the limiting part can play a limiting role. At the same time, it is also convenient to replace the connecting rod 5, which can reduce the time cost of the assembly line during operation and maintenance.

[0071] In other embodiments, different from the above-mentioned embodiments, in the present embodiment, the limiting portion includes a limiting groove and a limiting protrusion, the limiting groove is a "Z"-shaped groove arranged on the peripheral surface of the connecting rod 5, the limiting protrusion is a strip-shaped protrusion which is provided with the side wall of the limiting hole and extends axially, and the "Z"-shaped groove matches the strip-shaped protrusion, so that the strip-shaped protrusion can slide in the "Z"-shaped groove during the movement or rotation of the connecting rod 5. Furthermore, the strip-shaped protrusion can be arranged as a telescopic structure to facilitate the assembly of the connecting rod 5 and the limiting seat. This arrangement can prevent the connecting rod 5 from axially moving during the operation of the assembly line by moving the strip-shaped protrusion into the transverse groove of the "Z"-shaped groove so that the connecting rod 5 can move axially relative to the limiting seat, thereby ensuring the stable operation of the carrier 4.

[0072] Further, such as Figure 3 , Figure 8 and Fig. 9 As shown, when there are multiple chains 10 in the driving assembly, in some embodiments, the limit seat includes a first limit support 11 and a second limit support 12, wherein the first limit support 11 is fixedly arranged on the chain 10 close to the support plate and has a first limit hole 18 (specifically, as shown in FIG. 1 ) that allows the connecting rod 5 to pass through. Figure 8 The second limiting support 12 is fixedly arranged on the chain 10 away from the support plate, and has a second limiting hole 19 (specifically as shown) that allows the connecting rod 5 to pass through and is coaxially arranged with the first limiting hole 18. Fig. 9 In the assembled state, the connecting rod 5 passes through the first limiting hole 18 and the second limiting hole 19 at the same time, and is slidably connected with the first limiting support 11 and the second limiting support 12. By providing the first limiting support 11 and the second limiting support 12, the stability of the connecting assembly can be further improved, and the connecting rod 5 can be prevented from shaking or deflecting during the movement, thereby ensuring the stable operation of the carrier 4.

[0073] In addition, if Figure 3 and Fig.10As shown, on the basis of the above, the limiting protrusion in the limiting part is arranged on the connecting rod 5, including the first protrusion 21 and the second protrusion 22 arranged at intervals on the peripheral side surface of the connecting rod 5, and the second protrusion 22 is located on the side of the first protrusion 21 away from the support plate, and is located between the first limiting support 11 and the second limiting support 12, and the first limiting hole 18 is provided with a strip groove 20 that allows the first protrusion 21 to pass through and can prevent the second protrusion 22 from passing through. When the above-mentioned connecting assembly is not connected to the carrier 4, the second protrusion 22 is stuck on the upper surface of the second limiting support 12, and the connecting rod 5 is completely hidden under the support plate. When the connecting assembly needs to be connected to the carrier 4, the connecting rod 5 is rotated to make the first protrusion 21 correspond to the position of the strip groove 20 in the first limiting hole 18, so that the first protrusion 21 can pass through the first limiting hole 18 when the connecting assembly moves toward one side of the support plate. In this way, after the first protrusion 21 passes through the first limiting hole 18, the connecting rod 5 is rotated to make the first protrusion 21 misaligned with the strip groove 20, so that the connecting rod 5 can be maintained in a state of extending above the support plate. At the same time, under this setting mode, when the connecting rod 5 needs to be replaced, it is only necessary to disassemble the first limiting support 11 or the second limiting support 12, and the disassembly and replacement of the connecting rod 5 is relatively convenient.

[0074] Furthermore, the distance between the first protrusion 21 and the second protrusion 22 is equal to the axial length of the first limiting hole 18. In this way, when the connecting rod 5 is in a state of extending above the support plate, the first limiting support 11 cooperates with the first protrusion 21 and the second protrusion 22 to limit the axial movement of the connecting rod 5, preventing the connecting rod 5 from axially moving during the operation of the assembly line, thereby ensuring the stable operation of the carrier 4.

[0075] It should be understood that the above is only an example of the connection assembly including the limit seat and the connection rod 5, and the implementation method of the connection assembly is exemplified, but the utility model is not limited to this. For example, the connection assembly can also be an electric push rod or a hydraulic push rod fixedly arranged on the chain 10, and the telescopic end is arranged toward the annular opening 15. For another example, the connection assembly can also be a limit seat and a telescopic rod fixedly arranged on the limit seat, and the telescopic end of the telescopic rod can extend out of the annular opening 15.

[0076] Further, on the basis that the connection assembly includes the above-mentioned limit seat and the connection rod 5, in order to facilitate the connection rod 5 to extend from the bottom of the support plate to the top of the support plate, in some embodiments, such as Fig.10 As shown, a lifting ring 23 is provided on the end surface of the connecting rod 5 close to the support plate, and a "J"-shaped rod that can pass through the lifting ring 23 is provided. In this way, when the connecting rod 5 needs to be extended above the support plate, the lifting ring 23 on the connecting rod 5 is hooked with the "J"-shaped rod, and a force is applied toward the side away from the support plate. Of course, in specific implementation, the lifting ring 23 can also be replaced by a structure such as a hook.

[0077] Furthermore, in order to enable the carrier 4 to stably move along the annular opening 15 and prevent the carrier 4 from deviating during the movement, a guide assembly may be provided on the support plate, for example, Figure 4 As shown, the guide assembly includes a guide rail assembly and a guide wheel 24, wherein the guide rail assembly is arranged on the surface of the support plate, and includes a first guide rail 13 and a second guide rail 14 respectively arranged on both sides of the annular opening 15, and the guide wheel 24 is rotatably arranged on the carrier 4 and is rollingly connected with the guide rail assembly. Furthermore, a wheel rim is arranged on the inner side and / or the outer side of the guide wheel 24 to improve the guiding effect of the guide assembly.

[0078] As mentioned above, the surface of the support plate has an annular opening 15. In some embodiments, the support plate includes a support inner plate 1 and a support outer plate 6, wherein the support outer plate 6 has a through hole capable of accommodating the support inner plate 1 so as to be able to be sleeved on the peripheral side of the support inner plate 1 to form the annular opening 15.

[0079] In addition, the support assembly in the present invention further includes a support column 7 for supporting the support plate, and a fixed shaft sleeve 16 is sleeved on the support column 7 and rotatably connected to the support column 7 .

[0080] Furthermore, it also includes a side plate 2, which is arranged around the circumference of the assembly line and cooperates with the support plate and the upper surface of the foundation 3 to form a receiving cavity for accommodating structures such as a driving component and a connecting component.

[0081] The basic principle of the present invention is described above in conjunction with specific embodiments. However, it should be pointed out that the advantages, strengths, effects, etc. mentioned in the present invention are only examples and not limitations, and it cannot be considered that these advantages, strengths, effects, etc. must be possessed by each embodiment of the present invention.
